CABLEWAY CARRIAGE.

invented certain newand useful Improve- -ments in Cableway Carriages, of which the following is a specification.

My invention relates to cableway systems and carriages therefor, and particularly to cableways such as areused in logging.

The chief object of my invention is the provision of means whereby a running hoist line in its passage through the carriage and the fall block will at all timesbe bent in one .direction, thereby avoiding alternate bending of'the hoist line in opposite directions and reducing the internal friction'and wear in such cables.

)In the accompanying drawings I have shown my invention in forms of construe tion which will illustrate the principles thereof. I

Figure -1 shows a cableway carriagehaving my invention embodied therein, one side plate being removed to better show the posiv Figure 2 is a horizontal transverse section through that part of the carriage containing the, hoist rope pulleys.

" -Figure 3 is a view similar to that of Figure 1, but modified to fit a double or looped main line or trackway cable.

So far as the novel features of my invention are concerned, the carriage may be constructed in any suitable manner, and likewise may be supported and controlled in any suitable manner, itbeing'immaterial to the principal feature of my invention how thec'arri'age is constructed or traversed, but

'in'Figure 1 for convenience I have shown a carriage, whlch may consist of side plates 6, suitably joined, as supported upon a trackway cable 10 by means of trackway sheaves 1, 2 and 3, mounted in arms 4 and 40, the carriage proper being suspended therebelow by means of links 5. Inthis form the haulin line 13 and the back-haul line 14' bothl are shown as connected directly to the carriage, although this is a matter of choice and any convenient arrangement may be employed by means of which the carriage may be traversed along the line 10.

In Figure 3 the trackway cable is shown as looped to provide a second run 10, the

Application for carriage being supported from both of the lines 10 and 10, as by the addition of sheaves 1, 2', and 3', supported in arms 4 and 40, and these arms being connected through link 5 with the arms 4 and 40 which carry the trackway sheaves 1, 2 and 3.

In the common type of carriage wherein the hoist line is a running line, that is, one which is secured at one end, and which passes through the carriage and has a hoist block, as'9, in the depending loop of the line, it passes about two such pulleys, as 7 and 8, positioned in a common plane, and between these about the hoist block 9, thus bending the line three times in successively opposite directions. Such opposite bending of the line is much harder upon it, producing much greater internal friction than where the bending is all in the same direction.

Instead of following the above plan I provide means whereby the running hoist line is guided in such a way that in running through the carriage it crosses itself and is bent in only one direction.

In the form shown herein this is accomplished by the provision of two additional sheave wheels or pulleys, 7 O and 80, the two parts of the running hoist line 11 crossing in their passage'between the upper and the lower sheaves. By this expedient the bending of the line is everywhere in the same direction and also the angle of bend when passing about the sheaves in the carriage is reduced.

To prevent friction between the two crossed parts of the rope, the sheaves 7, 70, 8 and 80 of the carriage are of double width, having the line-receiving grooves 71 and 81 at one side, the other side being provided with a flange 78, preferably slightly coned so as 'to deflect the line if it ever bears thereon,

into the proper groove. The sheaves 7 and 70 have their grooves placed at one side of the carriage and the sheaves 8 and 80 at the opposite side. ll these sheaves may be alike in construction, two being turned oppositely to the other two. By such an expedient the cross parts of the line 11 are prevented from rubbing together. In logging, operations, in which cableway car 3,5 eference.
